What do supramolecular complexes do? - answer-; they are used for molecular recognition. they retain
individual units but stick to one another for a period of time until their job is done and then they break
apart
What's an example of a supramolecular complex? - answer-; ribosomes
What is the dalton unit? - answer-; mass unit of dalton (Da) to express mass of large molecules
25,000 g/mol = 25,000 Da = 25 kDa (kilodalton)
What is the level of organization for cellular molecules? - answer-;
monomers>macromolecules>supramolecular complexes
Describe the shape and size of cells - answer-; different shapes and sizes (spherical, rod-shaped, cubed)
range from 1 micron to 100 microns
What is the plasma membrane? - answer-; cellular space where processes of life occur that separates
life from non-life
What is the plasma membrane made up of? - answer-; lipids and non-polar proteins, these make the
membrane impermeable to water, ions, and large molecules
, What permits molecules across the plasma membrane? - answer-; Proteins in membrane allow
molecules like water, ions, nutrients, to cross in either direction
What is morphology? - answer-; form and structure of an organism
What's the main difference between eukaryotes and prokaryotes - answer-; eukaryotes contain
membrane-bound organelles while prokaryotes do not
Describe prokaryotes - answer-; -Bacteria and other single-celled organisms
-Unicellular, simple
-Smaller (1 um to 10 um)
-Cytoplasm
-Nucleoid
-Metabolites
Describe eukaryotes - answer-; -Humans, plants, animals, algae, fungi
-Larger, multicellular organisms (5 um to 100 um)
-Cytoplasm
-Organelles!
-Cytoskeleton
-Nucleus
-Nuclear envelope
-Ribosomes
-Smooth ER
-Golgi apparatus
-Peroxisome
-Lysosome
-Mitochondria
